What Is Area Code 312?

Area code 312 is one of the most iconic area codes in the United States. It is located in Illinois, and it specifically serves the heart of Chicago, one of America’s largest and most vibrant cities. If you receive a call from 312, it’s likely coming from someone in downtown Chicago.


The History of Area Code 312

The story of area code 312 begins in 1947, when it was first introduced as one of the original area codes created by AT&T and the North American Numbering Plan (NANP). Back then, 312 covered a much larger area, including most of northern Illinois. Over time, as the demand for phone numbers grew, the 312 area code became more focused on Chicago’s downtown area.

Here’s a timeline of how it evolved:

  1. 1947: Area code 312 is introduced, covering most of northern Illinois.
  2. 1989: Area code 708 is created, splitting off from 312 to serve the suburbs of Chicago.
  3. 1996: Area code 773 is introduced, further dividing the 312 area to cover the rest of Chicago outside of downtown.
  4. 2009: Area code 872 is added as an overlay for both 312 and 773 to meet the growing demand for numbers.

Where Does Area Code 312 Cover Today?

Today, area code 312 is strictly limited to downtown Chicago and the Loop. The Loop is the central business district of Chicago, home to many famous landmarks, skyscrapers, and businesses.

Some of the key neighborhoods and areas served by 312 include:

  • The Loop: Known for iconic buildings like the Willis Tower (formerly Sears Tower) and Millennium Park.
  • River North: A trendy neighborhood filled with restaurants, art galleries, and nightlife.
  • West Loop: Home to some of Chicago’s best dining spots and tech startups.
  • Near North Side: Includes the famous Magnificent Mile and Navy Pier.

If someone has a 312 number, they’re likely in the bustling heart of Chicago.


Why Is Area Code 312 So Iconic?

The 312 area code is a symbol of prestige and history. It’s one of the original area codes, which makes it stand out in a world of newer overlays and splits. In Chicago, having a 312 number often signifies a connection to the city’s core.

For businesses, a 312 number can give the impression of being well-established and located in the center of one of the country’s most important cities. For individuals, it’s a badge of honor that ties them to Chicago’s rich cultural and historical heritage.


How to Get a 312 Number

If you want a 312 number, you might find it challenging due to its limited availability. Since the 312 area is small and highly sought after, most new numbers in Chicago are now assigned from the 872 overlay. However, it’s still possible to get a 312 number through some phone service providers, especially if they have recycled or unused numbers.


Fun Facts About Area Code 312

  • Home to Iconic Landmarks: Area code 312 includes landmarks like Millennium Park, the Art Institute of Chicago, and the Chicago Riverwalk.
  • Featured in Pop Culture: 312 has been referenced in songs, movies, and TV shows as a symbol of Chicago.

The Future of Area Code 312

As the demand for phone numbers continues to grow, area code 312 remains one of the most exclusive codes in the country. The 872 overlay ensures that there are enough numbers for new users, but 312 will always hold a special place as the original area code of downtown Chicago.
